Well, well, what's this? We were just sent this obvious mockup of an ESPN Xbox 360, which our tipster found just hanging out on a Microsoft PR server. Now, this could just be a branding exercise or the remnants of a failed idea, but now that ESPN 3 is live on the Xbox 360 Fall 2010 Dashboard Update, it makes sense for the two companies to explore a branded console -- we know a lot of college students (and Engadget editors) who'd love to ditch their cable and still get ESPN through their 360s. We'll see what comes to pass -- and if Microsoft wisens up and tones down that red.
